My question was because constantly we received brute force attack from some of ip address which uses pop3 service to affect dovecot's login proccess.
This is quickly becoming an FAQ...
If this is linux, and these attacks are from the *same* IP address(es) (sounds like that is the case), then your best option is something like fail2ban. If, however, they are from bots that change IP address each time, fail2ban won't be effective...
